Dave,
You don't get a true picture of what will happen until you have sap boiling in the pan. The flues will always boil harder, but don't worry, the syrup will end up at the draw off valve when dense enough. Just keep a good hot fire and keep adding sap where instructed.
The first draw off will take what seems to be way too long, but it will happen. Just have enough sap to boil hard at least 3 hrs before first firing the arch up to get enough sugar in the pans to protect it from freezing. After that first time, you can boil each time you have enough sap to boil, but I suggest you don't boil if you don't have at least 2 hours worth boiling time. Too many short boils results in darker syrup.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
